[0032] Referring to Figures 1 to 4 The present application provides a sleeve pre-buried centering locator, comprising: movable plates 1, a distance adjusting assembly 2, and a locking assembly 3.

[0033] The movable plates are two in number. The two movable plates are oppositely arranged.

[0034] In the present embodiment, the limiting plates 21 are circular. The two limiting plates 21 are coaxially arranged.

[0035] Specifically, each movable plate has an inner side and an outer side. The inner sides of the two movable plates are oppositely arranged. One movable plate 1 has an outer side abutting against the side surface of the pre-buried sleeve 4. The outer side of one movable plate 1 is provided with a clamping piece 11 for clamping the wall of the pre-buried sleeve 4.

[0036] In construction, the pre-buried sleeve is arranged in the to-be-installed hole. The two movable plates are arranged between the pre-buried sleeve and the inner wall of the to-be-installed hole. The outer side of one movable plate abuts against the circumferential surface of the pre-buried sleeve, and the outer side of the other movable plate abuts against the inner wall of the to-be-installed hole.

[0037] The distance adjusting assembly 2 is used to adjust the distance between the two movable plates, so that the outer side of one movable plate abuts against the circumferential surface of the pre-buried sleeve, and the outer side of the other movable plate abuts against the inner wall of the to-be-installed hole.

[0038] Specifically, the distance adjusting assembly comprises limiting plates 21, a shaft 22, a gear 24, driving racks 23, and a counterforce piece 25.

[0039] The limiting plates are two in number. The two limiting plates 21 are oppositely arranged. The two limiting plates 21 are arranged along the length direction of the pre-buried sleeve 4. The limiting plates 21 are provided with shaft holes. The shaft holes are arranged at the planar centers of the limiting plates. The shaft 22 is rotatably arranged in the shaft holes of the two limiting plates 21. The middle part of the shaft 22 is coaxially connected with the gear 24. The gear 24 is meshed with the two driving racks 23 at opposite sides. The two driving racks 23 are movably arranged between the two limiting plates 21. The opposite ends of the two driving racks 23 respectively extend to the outside of the limiting plates 21 and are respectively connected with the two movable plates 1. The limiting plates 21 are formed with the counterforce piece 25 abutting against the opposite sides of the two racks 23.

[0040] The locking assembly 3 is used to lock the gear 24. The locking assembly 3 is arranged on the limiting plate 21.

[0041] As a preferred embodiment, referring to Figure 3 and Figure 4As shown, the outer side of the other movable plate 1 is formed with a support flange 13 for abutting against the outer end of the to-be-constructed hole 50. By means of the support flange, the sleeve pre-embedded centralizer can be stably arranged in the orifice of the to-be-installed hole.

[0042] Referring to Figure 1 and Figure 2 As shown, the locking assembly 3 comprises a rotating lever 31 and a plug rod 32.

[0043] A limiting plate 21 is provided with a first slot. In the embodiment, the limiting plate close to the orifice of the to-be-installed hole is provided with the first slot. The rotating lever 31 is reversibly arranged in the first slot, i.e. the length of the first slot is much greater than the outer diameter of the rotating lever, so that the rotating lever can be reversed in the first slot. Preferably, the width of the first slot is adapted to the outer diameter of the rotating lever. The two ends of the rotating lever 31 respectively extend to the inner and outer sides of the limiting plate 21.

[0044] The plug rod 32 is connected to the end of the rotating lever 31 extending to the inner side of the limiting plate 21. The outer diameter of the plug rod is adapted to the distance between the two adjacent teeth of the gear. After the distance between the two movable plates 1 is adjusted to the preset distance, the rotating lever 31 is reversed to allow the plug rod 32 to be arranged between the two adjacent teeth of the gear 24, thereby locking the gear 24.

[0045] In some embodiments, a fixed shaft is connected in the first slot. The middle part of the rotating lever 31 is provided with a through hole. The fixed shaft is reversibly arranged in the through hole.

[0046] In the embodiment, the opposite sides of the limiting plate 21 are respectively provided with second slots (not shown in the drawings). The second slots are arranged along the thickness direction of the movable plate 1. Preferably, the second slots are arranged in the same direction as the first slot, and the two second slots are respectively arranged on the opposite sides of the first slot. The two second slots are reversibly provided with inclined limiting rods 12. One end of the inclined limiting rod 12 in the two second slots is respectively hinged to the opposite sides of one movable plate 1. The other end of the two inclined limiting rods 12 respectively abuts against the opposite sides of the other movable plate 1.

[0047] Correspondingly, the length of the second slot is much greater than the outer diameter of the inclined limiting rod, so that the inclined limiting rod can be reversed in the second slot. Preferably, the width of the second slot is adapted to the outer diameter of the inclined limiting rod. When the distance adjusting assembly adjusts the distance between the two movable plates, the other movable plate can ensure the movement along the limiting space formed between the two inclined limiting rods.

[0048] The present application provides a construction method of a sleeve pre-embedded centralizer, comprising the following steps:

[0049] S1: arranging the pre-embedded sleeve 4 in the to-be-constructed hole 50.

[0050] S2: provide at least three sets of sleeve embedded centering locators, and the outer side of the movable plate 1 is attached to the side of the embedded sleeve 4, and the clamping member 11 on the outer side of the movable plate 1 clamps the pipe wall of the embedded sleeve 4, so that the at least three sets of sleeve embedded centering locators are arranged at intervals along the circumferential direction of the embedded sleeve 4, and the other movable plate 1 of the at least three sets of sleeve embedded centering locators is arranged to face the inner wall of the to-be-constructed hole 50.

[0051] Preferably, as shown in the drawings, Figure 3 The three sets of sleeve embedded centering locators are arranged at equal intervals along the circumferential direction of the embedded sleeve.

[0052] S3: Rotate the rotating shaft 22 of the distance adjusting assembly 2 to make the two movable plates 1 face away from one end, so that the other movable plate 1 is pressed against the inner wall of the to-be-constructed hole 50.

[0053] S4: Lock the locking assembly 3 gear 24 on the limiting plate 21 to lock the distance between the two movable plates 1.

[0054] S5: Embed the support block 60 between the adjacent two sets of sleeve embedded centering locators, the inner wall of the to-be-constructed hole 50, and the sleeve.

[0055] S6: Remove the sleeve embedded centering locator for recycling.

[0056] The gear of the distance adjusting assembly of the sleeve embedded centering locator of the present application has half a millimeter scale as one gear tooth, and a numerical machine tool is used to process and repair the gear. The front and rear gear center points are positioned by laser to ensure that they are on the same center line. After the rotating shaft penetrates the center point, the position is adjusted and then welded, and post-welding treatment is done. Only rotating the rotating shaft can achieve high-precision distance adjustment, which improves the precision and quality of the embedded sleeve and reduces the loss caused by rework of the embedded sleeve.

[0057] By arranging the support flange flush with the hole of the to-be-installed hole, when the embedded sleeve is fixed and installed, the support flange is tightly attached to the outside of the hole of the to-be-installed hole, and the distance between the two movable plates is adjusted by the rotating shaft, so that the sleeve embedded centering locator is stably arranged between the to-be-installed hole and the embedded sleeve, and after the rotating shaft of the distance adjusting assembly of the multiple sleeve embedded centering locators is rotated by the same angle, the distance between the two movable plates can be quickly adjusted synchronously, and the embedded sleeve is installed in the to-be-installed hole, thereby improving the embedding construction efficiency of the embedded sleeve.

[0058] The support block is inserted into the gap (the space between the outer wall of the embedded sleeve and the hole wall of the to-be-installed hole) according to the distance between the embedded sleeves after positioning, and the end faces are flush, thereby solving the problem of manual waste such as the need for special personnel to look after the sleeve embedding in the traditional construction process and the inability to fully cover and track, improving the embedding quality while reducing unnecessary labor costs.

[0059] The construction method of the sleeve pre-buried centering locator of the present application is the same as the sleeve installation, three sets of sleeve pre-buried centering locators are used, three-point positioning a plane, ensuring the consistent spacing between the pre-buried sleeve and the to-be-installed hole. After the centering is completed and fixed by the support block, the multiple sleeve pre-buried centering locators can be disassembled and used for the positioning of the following pre-buried sleeve, thereby improving the sleeve pre-buried efficiency and effect, and the repeatedly used complete device also has certain economic benefits.
